Separability, which is a non-woven material, forming a protrusion in the non-woven material outwardly extending from the first surface of the non-woven material and a wide base opening adjacent to the second surface of the non-woven material. A nonwoven fabric having the following three-dimensional deformation is disclosed. The width of the protrusion can vary along the length of the protrusion.不織布材料であって、不織布材料の第1表面から外向きに延出する突出部と、不織布材料の第2表面に隣接する幅広の基部開口部とを、それ自体の中に形成する、分離性の3次元変形を有する不織布が、開示される。突出部の幅は、突出部の長さに沿って変化し得る。
